Ian identified UGA, normally a ‘STOP’ codon, as encoding the 21st amino acid selenocysteine.
Ian is co-discoverer of Nanog, a pluripotent-specific transcription factor that can confer LIF-independent ES cell self-renewal. Ian therefore named Nanog after TirnanOg, the Celtic Land-of-the-Ever-Young. This work was cited as a “landmark achievement in UK research” in the UK Stem Cell Initiative Pattison Report.
